  • Loubser, Nicolas Johan (Stellenbosch : Stellenbosch University, 1984-11)
    AFRIKAANSE OPSOMMING: Hierdie tesis behels 'n ondersoek na die geskiktheid van 'n datavloei-verwerker om as 'n herstruktureerbare spesiale verwerker te dien. Die werking van 'n datavloei-verwerkermodel word aan die ...
  • Zhang, Haoyi (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: The concept of National Innovation System (NIS) as new conceptual framework appeared in the late 1980s. The framework of NIS not only focuses on the science and technology development of a country, but ...
  • Van der Merwe, Johannes Wilhelm (Wim) (Stellenbosch : University of Stellenbosch, 2011-03)
    AFRIKAANSE OPSOMMING: Hierdie proefskrif handel oor die natuurlike balanserings meganismes van veelvlakkige en modulêre omsetters wat fase-skuif dragolf puls wydte modulasie gebruik. Die meganismes kan in twee hoof groepe ...
  • Wilkinson, Richardt Howard (Stellenbosch : University of Stellenbosch, 2004-04)
    ENGLISH ABSTRACT: Multilevel converters were developed as a result of a growing need for higher power converters. This dissertation addresses a specific multilevel topology called the multicell topology. A problem associated ...
  • Salagae, Isaac Mahijoko (Stellenbosch : Stellenbosch University, 2003-12)
    ENGLISH ABSTRACT: The three-level neutral-point-clamped(NPC) converter, being a widely used multilevel inverter, received a lot of attention recently due to problems associated with de-link capacitor voltage balancing. ...
  • Salagae, Isaac Mahijoko (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The multicell inverter, being a widely used multilevel converter, has received much attention in recent years due to problems associated with cell capacitor voltage. In this dissertation we study the ...
  • Roberts, Theari (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The world is facing an energy crisis with worldwide energy consumption rising at an alarming rate. The effects that fossil fuels have on the environment are also causing concern. For these two reasons ...
  • Garth-Davis, Bryan (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: In percutaneous procedures, where the surgeon inserts a needle into a target in the patient, it is challenging to access the target at the rst attempt. Repeated needle insertion attempts are highly ...
  • Maritz, Gert Stephanus Herman (Stellenbosch : University of Stellenbosch, 2011-12)
    ENGLISH ABSTRACT: The perceived quality of Voice over Internet Protocol (IP) (VoIP) communication relies on the network which is used to transport voice packets between the end points. Variable network characteristics ...
  • Muller, Martinette (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: The application of artificial neural networks to microwave circuits is investigated. A neural network model is developed for two parallel waveguides coupled by a longitudinal slot in the common broad ...
  • Conradie, Alex van Eck (Stellenbosch : University of Stellenbosch, 2004-12)
    ENGLISH ABSTRACT: A Neurocontrol Paradigm for Intelligent Process Control using Evolutionary Reinforcement Learning Balancing multiple business and operational objectives within a comprehensive control strategy is a ...
  • Conradie, Alex van Eck (Stellenbosch : Stellenbosch University, 2000-04)
    ENGLISH ABSTRACT: The growth in intelligent control has primarily been a reaction to the realisation that nonlinear control theory has been unable to provide practical solutions to present day control challenges. ...
  • Van Greunen, Corneluis Erasmus (Stellenbosch : University of Stellenbosch, 2005-03)
    This thesis presents the design and implementation of a Neutral-Point-Clamped (NPC) shunt Active Filter (AF) for non-linear loads. A NPC shunt AF is an attractive solution for AFs at the medium volage level, because it ...
  • Van Zyl, Wiehann (Stellenbosch : University of Stellenbosch, 2008-03)
    The aim of this research was to investigate new product development practices for application to small businesses. Although larger companies, in general, have well-established practices from which smaller companies can ...
  • Van der Westhuizen, Ewald (Stellenbosch : Stellenbosch University, 2003-12)
    ENGLISH ABSTRACT: Two non-destructive methods of extracting audio from Edison phonographic cylinders were investigated. A recording device with high accuracy positioning was designed and manufactured. A microscopic image ...
  • Du Toit, Ilze (Stellenbosch : University of Stellenbosch, 2004-12)
    ENGLISH ABSTRACT: In this study the phoneme labels derived from a phoneme recogniser are used for phonetic speaker recognition. The time-dependencies among phonemes are modelled by using hidden Markov models (HMMs) for ...
